WTSGateway When installed on any Windows 2000 or XP machine, WTSGateway act as a gateway for both RDP and citrix ICA protocols. This means you do not need to expose your whole network to the outside. On this machine you will add the IP addresses of all your Terminal Servers and WTSGateway will balance the load among the servers, establishing the connection directly between the WTSGateway and the Terminal Servers.
